GEORGE A. MILLER, OF DES MOINES, IOWA, ASSIGNOR OF ONE-HALF OF HIS RIGHT TO B. Y. FLINN, OF SAME PLACE;

lNK-ROLLER ATTACHMENT FOR PRlNTlNG 'MACHINES.

SPECIFICATION forming part of Letters Patent No. 232,744, dated September 28, 1880. Application filed July 13, 1880. (N 0 model.)

To all whom it may concern:

Be it known that I, GEORGE A. MILLER, of Des Moines, in the county of Polk and State of Iowa, have invented a Printing-Press Attachment for Holding and Adjusting Ink-Rollers, of which the following is a specification.

The object of my invention is to provide a simple attachment that can be readily applied to a printing-press to hold and adjust the form-rollers relative to the bed and form and the ink-distributing roller.

Heretofore roller-bearers have been placed on fixed brackets having inclined planes and pushed and pulled up and down thereon by means of screws to accomplish the results contemplated; but it frequently occurs that this one means of adjustment is insufficient when the rollers become worn and are not uniform in size, and therefore I provide a means for adjusting the bearings of the form-rollers in two directions on the inclined planes, and also by adjusting the inclined planes relative to the frame of the press, the form, and the inking apparatus.

Figure 1 of my drawings is a top-plan view. Fig. 2 is a side elevation of my device attached to a section of the frame of a press. Fig. 3 is a sectional view through the dotted line w 90 in Fig. 2, showing the adjustable pivoting-bolt in contact with the shaft of a form-roller. Jointly considered, these figures fully illustrate the construction, application, and operation of my complete invention.

a a represent the frame of a printing-press, which may vary in configuration. b b are upright portions of the frame a a, that support the ink-distributin g roller 0. The bearings for this roller 0 may be formed in or attached to the frame portions 1) in any suitable way.

at is the main portion and upright part of the frame and base of my attachment. It has a vertical slot, 6, in its center, through which a bolt, f, is passed to clamp it to the pressframe part b.

g g are arms formed integral with the part d, to produce two uniformly-inclined planes that extend in opposite directions from its lower end to support sliding blocks h h, to which the form-roller bearers k k are attached. The sliding blocks it have longitudinal slots i,

through which thumb-screws m are passed to clamp them upon the inclined arms g. These blocks h also have enlargements at their inner ends, that form socket-bearings for the lower and rounded ends of the elbow-shaped roller-- bearers 70, that are thus fitted to the blocks in such a manner that they can be revolved and raised and lowered and rigidly blocked, when required, by means ofset-screws a. By turning the swiveled rollerbearers the journals of the form-rollers s s are more easily inserted than when the bearings are rigidly fixed.

s are bolts passed horizontally through the bearings to pivot the rollers s, and to thereby make them run truer and with less friction. They are adjustable and locked by means of thumb-screws r.

w w are extensions on the under sides of the inclined arms g. They have slots 00, through which set-screws g are passed into the frame a, to aid the screw-boltf in clamping the adjustable frame at g g to the press-frame.

a z are bearings formed on or attached to the upright part b of the frame a, to aid in retaining my attachment in a perpendicular position at all times, and to hold it perfectly rigid when the press is in operation.

In the practical use of my invention thus constructed and applied each form-roller 8 may be readily removed by simply loosening the thumb-nut m and revolving the sliding block it, carrying the roller-bearer 7c outward to free the end of the roller-shaft from the bearer and the pivoting-bolt 8 carried thereby.

To adjust the complete attachment relative to the form and the inking apparatus, the screws f and y 3 can be loosened and the upright 61 moved vertically in its bearing 2.

To adjust the form-rollers the swiveled bearings k can be readily raised andlowered in their sockets by loosening the set-screws a, or by loosening the set-screws m and sliding the blocks h on the inclined arms g. By this triple means of adjusting the form-rollers relative to the form and the ink-distributing roller the color can be more uniformly applied to the paper and improved press-work performed.

I claim- 1. The press-frame a a, having fixed bearings z 2 on its upright part b, the attachmentframe (I g g w we, having slots 6 00 ac to admit screw-bolts f y 3 formed, arranged, and combined as shown and described, to operate in the manner set forth.

2. The elbow-form roller-bearers k To, carrying the pivotal bolts 8 and thumb-screws 1', in combination with the adjustable blocks and sockets h, carrying set-screws n, substantially as and for the purposes shown and described.

3. The sliding blocks h, having slots 6 and carrying the swiveled roller-bearers k, in combination with the inclined arms g, carrying the and described.

GEORGE A. MILLER.
